"BaaBaa black sheep have you any wool? Yes Sir, yes Sir, three bags full. One for the master and one for the dame, and one for the little boy who lives down the lane".

The wool is used to make warm clothes, and one pullover became yours.  Now after many winters, it is worn or even torn.

Washed very hot it will shrink to half the size but the wool is still warm and very soft. 

Now it can become a little sheep for someone who loves you.
